Song Yuncheng poked her head out from under the covers and saw Chen Yansen sitting upright at the desk in the living room.

Chen Yansen heard the movement behind him but didn't look up, continuing to flip through *The Character of Physical Law*.
Ever since his required sleep time had shortened, his way of passing the time had become reading these obscure and difficult physics and math books.
In Chen Yansen's eyes, however, this material was as simple as elementary school arithmetic.
